Abstract
Dalam pelaksanaan kegiatan pemeliharaan, Unit Pelayanan Pemeliharaan Wilayah Timur (UPHT) mempunyai tiga target utama yaitu on quality, on cost, dan on time. PT PJB menginginkan UPHT untuk melakukan optimalisasi durasi waktu overhaul. Adapun strategi yang dikaji adalah mendetailkan work breakdown structure (WBS), bekerja dalam 2 shift, roll in – roll out spare part, dan pembentukan tim quality control yang berkompetensi. Pada penelitian ini, aktivitas value added, non-value added, necessary added, dan beban kerja dianalisis untuk mengoptimalkan kualitas, durasi, profit dan meminimalisir budget pada manajemen proyek overhaul unit turbin gas. Instrumen yang digunakan dalam penelitian adalah Yamazumi Chart dan NASA-Task Load Index (NASA-TLX). Hasil penelitian menunjukkan persentase aktivitas value added sebesar 38%, necessary non-value added sebesar 51% dan non-value added sebesar 11% dari waktu keseluruhan overhaul. Terdapat potensi mempersingkat durasi major overhaul perubahan jadwal kerja dari yang semula dijadwalkan selama 32 hari, menjadi hanya 18 hari dengan cara menggunakan pola 2 shift. Profit yang didapatkan dari penyingkatan durasi overhaul adalah Rp. 2.500.975.763,74

In the implementation of maintenance activities, East Region Maintenance Service Unit (UPHT) has three main targets, namely on quality, on cost, and on time. These three targets are a form of UPHT commitment in maintaining customer confidence on work result. PJB wants UPHT to optimize the duration of overhaul time. The possible strategy could be applied consists of detailing work breakdown structure (WBS), working in two shifts, roll in - roll out spare parts, and the establishment of a competent quality control team. In this research, value added, non-value added, necessary added, and workload activities were analyzed to optimize quality, duration, profit and minimize budget on project management overhaul gas turbine units. The instrument used in this study were Yamazumi Chart and NASA-Task Load Index (NASA-TLX). The results showed the percentage of value added activity was 38%, necessary non-value added was 51% and non-value added was 11% of the total overhaul. There is the potential to shorten the duration of the major overhaul changes in work schedules from those originally scheduled for 32 days, to only 18 days by using the two-shift pattern. The profit earned from shortening the duration of the overhaul is Rp. 2,500,975,763.74
